FIELD OF THE INVENTION

The present invention relates generally to shelf assemblies for use inmerchandising product and more particularly to shelf assemblies thatimprove the securement and management of merchandised product.

BACKGROUND OF THE INVENTION

It is known that retail and wholesale stores, such as drug stores,grocery stores, discount stores, toy stores, and the like require anduse a large amount of shelving both to store product and to display theproduct to consumers. In displaying product to consumers to promote andimprove store sales, these stores situate or position the product towardthe front of the shelf so that the product is visible and easilyaccessible to consumers. This desirable positioning has certaindrawbacks. For instance, with this desirable “front-facing” of product,the stores are finding that relatively small products or packages ofhigh value can be the target of thieves. Certain items can represent ahigh value to potential thieves who can either resell the items or usethem for other illegitimate purposes, as in the case of certainpharmaceutical products. This theft is increasing and is now asignificant cost to the retailer because thieves prefer to steal manyproducts at once or in as short amount of time as possible. To do this,for example, thieves will “sweep” the shelf with their arm collectingthe items into a purse, bag or coat very quickly and exit the storewithout drawing attention.

Theft can be the result of both customers and employees actions and hasbeen difficult to eliminate. Attempts to deter and prevent theft haveproven to be only partially effective. For instance, in-store camerasoften do not observe the theft clearly enough to catch or prosecute thethief In addition, in-store security personnel are rarely in the correctposition to actually observe a thief in action. As a result, theftcontinues to be a significant problem and cost in the management ofproduct inventory.

The present invention is directed at overcoming these and other knowndrawbacks and problems with existing shelving systems.

BRIEF SUMMARY OF THE INVENTION

The present invention overcomes the above-mentioned problems byaddressing the securement and management of product in a retail setting.As will become evident below, the invention has the ability to inhibit“sweeping” of product by a thief and to limit the taking of largeamounts of product from a shelf in a short period of time. Using one ormore methods such as placing the shelves closer together, using productdividers that extend from the front edge of the shelf and between theshelves, using a merchandising system that controls the speed of apusher, placing front walls having a specific height that results in asmaller opening to limit access to product, using an electronic controlunit and an electronic lock-out mechanism which locks the merchandisingshelf and multiple shelves when too many products are removed at onetime, the present invention will inhibit sweeping of product and theremoval of numerous products at a time. The present invention also hasthe ability to alert store or security personnel and security cameras ofa potential theft situation, while minimizing the impact on access toproduct by legitimate shoppers.

In an embodiment, a system for detecting the potential theft of productfrom a display shelf may comprise: at least one shelf for containingproduct, a barrier, and an alert device. The barrier may have a firstend mounted to the system, and a second end that cooperates with thefront edge of the shelf to inhibit access to the product on the at leastone shelf The barrier may extend towards the shelf and movable between aclosed position and an open position. The barrier may extend with thebarrier substantially blocking access to the at least one shelf when inthe closed position and permitting access to the at least one shelf whenin the open position and permitting removal of product from the front ofthe at least one shelf The alert device may be operatively connected tothe barrier by an air switch and a pressurized pneumatic tube connectedto the air switch and the pneumatic tube located adjacent to the firstend of the barrier. The alert device may detect movement of the barrierand provide an alert indicative of a potential theft of product from adisplay shelf

Additionally, the barrier may be pivotal from the closed position to theopen position.

The barrier may move from the closed position to the open position, withthe first end of the barrier pivoting to engage the pneumatic tubing,thereby compressing the pneumatic tubing, activating the air switch, andsending a signal to the alert device. Further, when the barrier movesfrom the open position to the closed position, the first end of thebarrier pivot may disengage the pneumatic tubing, thereby de-compressingthe pneumatic tubing and de-activating the air switch.

The system may further comprise a receiver for detecting the alert fromthe alert device with the alert from the alert device selected from thegroup consisting of an audible, inaudible, infrared, radio-frequency,cellular, ultrasonic, digital, analog, and electronic alerts. The alertmay be received by a processor for further signal processing. Thefurther signal processing may includes determining a total time thebarrier was in the open position, determining a frequency the barrierwas in the open position, or determining whether a theft situationexists.

Other features and advantages of the invention will become apparent tothose skilled in the art upon review of the following detaileddescription, claims and drawings in which like numerals are used todesignate like features.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to the securement, management, anddistribution of products in settings such as a retail setting andincludes numerous embodiments. One embodiment involves a shelfmanagement and display system that resides either on a standard orexisting “dealer” shelf typically found in a retail store or on a shelfdesigned with certain advantages in securing products and deterringtheft. The embodiment may include uprights of a pre-existing shelvingsystem or may be a stand alone unit. The display system includesfront-facing systems, which force product to the front of a shelf Suchsystems may use various methods, such as gravity, friction, magnetism,or spring-urged pushers or paddles to bring product to the front of ashelf near the aisle. Many examples of spring-urged systems that orientproducts toward the front of a shelf exist and include the systemsdescribed in U.S. Pat. No. 6,041,720 to Hardy, U.S. Pat. No. 4,830,201to Breslow, and International Application No. PCT/US02/15760 andcorresponding International Publication No. WO 02/091885 A1 to Hardy,which are incorporated herein by reference.

Referring to FIGS. 1 and 2, in one embodiment of the present invention,a shelf management and display system 100 includes vertical uprights 102and product shelves 104 removably mounted to the uprights. The shelves104 may be mounted at various positions along the uprights 102 dependingon the desired positioning and spacing of the shelves 104. Similarly,the shelves 104 may be moved or relocated to different positions alongthe uprights 102 as necessary. As shown in FIGS. 4 and 5, the shelves104 may be pull-out shelves that pull away from the uprights 102 likedrawers. As illustrated by FIG. 3, the shelf 104 may incorporate alocking device 117 which involves cooperating catches that contact eachother in the locked position and substantially release this contact inthe unlocked position and that when released will permit the shelf 104to pull-out and away from the uprights. The shelves or uprights mayinvolve other locking devices, such as magnets, latches, notches,binders, tension or the like. Once pulled away, the store personnel canrestock the shelf with product and then slide the shelf 104 back to itsoriginal position and relock the shelf

A back wall 106 may be mounted to the uprights 102 through knownmounting techniques to aid in containing the products and to preventaccess to the products from the back of the display system 100. A lockbox 108 may be mounted to the uprights 102 also through known mountingtechniques. The lock box 108 may be used for storing and lockingadditional product and shelving components for quick retrieval by thestore personnel. The lock box 108 may be positioned at any position onthe uprights 102, including the depicted positioning at or near the topof the display system 100. In an alternative embodiment, the lock box108 may be secured to a shelf 104 as opposed to the uprights 102. Witheither mounting location, the additional product and shelving componentsare located at the display system 100 and can therefore be readilyretrieved by store personnel.

An exemplary embodiment of the invention may include a series of wallsor dividers 110 that are placed between product rows, lanes or facings,and at the ends of the facings, to deter product “sweeping” by a thiefThese walls 110 are sometimes referred to as “product dividers.” As usedherein, the terms “vertical walls,” “product dividers” and “dividers”are meant to include any wall (including vertical and non-vertical),divider, barrier, or separator that may be used between product rows,lanes or facings. The product dividers 110, when positioned in aspaced-apart manner on the display system 100, form product lanes 112for locating and separating product to be merchandised.

The product dividers 110 or side walls also are positioned at the sidesof the product facing to prevent access to the product from the side ofthe display system 100. In one embodiment, these dividers or side wallsmay include telescoping features that permit them to extend verticallyor horizontally to provide additional product securement. Significantly,these dividers or side walls may be used in numerous applications as thesize and extent of these can be adjusted to fit most shelves, shelvingor display systems, or applications.

A pusher 126 can be used to urge product forward. This pusher canincorporate a coil spring to assist in urging product forward. Thedivider 110 in some embodiments can include a base or floor. In someembodiments this floor includes a pusher track 128. FIG. 6 shows thefloor on one side of the divider wall. A second floor can be on theopposite side of the divider wall. With floors on both sides of thevertical divider wall, product can rest on these floors. In one suchembodiment, a product can rest on one floor of one divider and a secondfloor of a second divider.

The product dividers 110 define a height, shape and configuration thatdeter the removal of product over the product dividers 110. The dividers110 extend in a vertical or non-vertical manner between the shelves 104and from the front of the shelf 104 to the back wall 106. The dividers110 have a generally rectangular shape; however, other shapes andconfigurations of the dividers, such as non-rectangular, oval, repeatingpatterns or the like, may be used with the invention. Depending on theproduct to be merchandised and the desired degree of access to theproducts, the front edge 114 of the product dividers 110 may extendvertically between the shelves 104, or may extend non-vertically to makethe products more accessible to the consumer and easier to remove fromthe shelf. In one embodiment, the divider 110 defines a front edge 111that includes a front edge portion 113 protruding outward from the frontedge 111, as shown in FIG. 5. The protruding portion of the front edgewill assist in holding the retaining wall or tab 122 in position toprevent slidable movement of the retaining wall or tab 122, as describedbelow.

The product dividers 110 may be mounted to the display system 100 usingnumerous techniques. As an example, the dividers 110 may be insertedinto tracks formed in the shelf 104 or tracks formed in a base thatattaches to the shelf 104. Similarly, the dividers 110 may be formedintegral or as a unitary unit with a base that is mounted to the shelfAlso, the dividers 110 may be mounted to a rail, channel, or groove asunderstood by those skilled in the art. The dividers 110 should besufficiently rigid to retain the product within the product lanes.Examples of dividers that may be used with invention are described inU.S. Pat. No. 6,041,720 to Hardy, U.S. Pat. No. 4,830,201 to Breslow,and International Application No. PCT/US02/15760 and correspondingInternational Publication No. WO 02/091885 A1 to Hardy, which areincorporated herein by reference. One skilled in the art will appreciatethat other dividers and techniques for mounting the dividers to theshelves are known and may be used with the teachings of the invention.

In one embodiment, the dividers 110 may have a step down or decline nearits rear edge, or a decrease in wall height, to allow the wall 110 to belifted and disengaged from the rail on which it is mounted. With thisconfiguration, the dividers 110 may be moved laterally withoutinterfering with the shelf above it. In one embodiment, the verticalwall or divider 110 has a step down beginning approximately ⅔ of thewall length from its front edge.

In an embodiment, it may be desired to provide enhanced security foritems on only a portion of a shelf These items may be located in thecenter of the shelf or on a side of the shelf Security features such asthose referenced herein can be added to only a portion of the shelf,while the remainder of the shelf contains fewer or none of the securityfeatures. Where high security items are placed in the center of a shelf,these items can be segregated from the remainder of the shelf throughthe use of walls. These walls can provide the side barriers for the highsecurity portion of the shelf These walls can be made of strongconstruction, such as metal, and can extend from the floor of a shelf toa distance fairly near the top of the shelf These walls also can beattached to the shelf as well as the other security features to limitthe possibility of the walls being bent, removed or otherwise thwartedand to assist in limiting access to the items being merchandised on theshelf

Referring to FIGS. 25, 30 and 31, walls 340 and 350 are used tosegregate a shelf into a higher security area and a lower security area.Walls 340 and 350 can be made from steel and can extend from at or nearthe floor of the shelf to an area at or near the ceiling of the shelf.The walls also can be adjustable. In an embodiment, the walls can becomprised of a top section 344 and a bottom section 346. As shown inFIG. 31, these two sections can overlap to provide a continuous barrier.The top section 344 of wall 340 and the bottom section 346 of wall 340can include apertures that align the two walls. A fastener 348 such as ascrew, bolt, pin, rod or other fastener can be used to join the twowalls at a particular height. The walls also can comprise a floor 342which includes apertures and can be connected to the floor of the shelfthrough a fastener 349 such as a screw, bolt, pin, rod or otherfastener.

Referring to FIGS. 74-78, in an alternative embodiment, the walls 340and 350 may be in the form of an adjustable wall 702 that is slidablymovable and repositionable. The wall 702 defines one or more elongatedchannels or slots 704 that permit movement of the wall 702 andadjustment of the location of the wall 702 to a desired position. In anexemplary embodiment, the channels 704 may be vertically andhorizontally oriented on the adjustable wall 702. The wall 702 may bemoved and positioned, as desired, and secured to a lower wall portion706 through the use of fasteners 708, such as screws, bolts, pins, rodsor or the like. The lower wall portion 706 may include numerous holes709 for receiving the fasteners 708 and may include a floor 710 whichmay include a plurality of holes 711 for mounting the floor 710 to theto the floor of the shelf as described above. For convenience inadjusting the wall 702 relative to the lower wall portion 706, a tool714, such a hex key, wrench, screw driver, or the like, may be mountedto the lower wall portion 706 to be used by a user to make the desiredadjustments of the location of the wall 702.

As should be readily apparent, the elongated channels 704 provide fornumerous mounting positions of the wall 702 relative to the lower wallportion 706. In an exemplary position, the wall 702 is fastened to thelower wall portion 706 such that the fasteners 708 are located atpositions 716 a and 716 b in the elongated channel 704. In thisposition, as shown by FIG. 75, the wall 702 will be in an unextendedposition. In one of the numerous alternate positions, the wall 702 maybe positioned and the fasteners 708 may be located at positions 716 cand 716 d. In this position, the wall 702 will be in an extendedposition such that the wall 702 extends upward relative to the lowerwall portion 706 and away from the lower wall portion. In this position,the wall 702 may serve as an additional barrier to inhibit access to theshelf and thereby further secure the products on the shelf As yetanother example, the wall 702 may be positioned and the fasteners 708may be located at positions 716 b and 716 e. In this position, the wall702 will be in an extended position such that the wall 702 extends awayfrom the lower wall portion and will be at the same height as the lowerwall portion. It should be readily apparent that numerous otherpositions of the wall 702 relative to the shelf are possible dependingon the desired level of security and the configuration of the shelf, andthe tool 714 provides convenience and ease of adjustment of the wall702. It should be understood that the elongated channel may definenumerous other configurations that still permit movement and adjustmentof the wall 702 relative to the lower portion. The system illustrated byFIGS. 74-78 may further be configured and mounted on either or both endsof the shelf, and if desired, to the front or rear of the shelf Also,the wall may be made of any suitable material, such as metal or plastic.

Referring to FIGS. 25-27, 30-33 a clip or clip member 320 or 360 may beused to further secure the wall 340, 350 to the shelf 104 and inparticular the walls that separate secure products from non-secureproducts. The clip 320, 360 also can be used to secure divider 110 to ashelf 104 (embodiment not shown). The clip 320, 360 may be used tostrengthen the wall 340, 350 to prevent the bending or moving of thewall. With the use of the clip 320, 360, the wall 340, 350 may be madeof a thinner, less costly material because the clip 320, 360 willprevent potential bending or twisting of the wall to access the producton the shelf The walls 140, 150 also are known as side walls.

In an exemplary embodiment, the clip 320, 360 is configured at one endto engage a hinge rail 322, which is used to hinge the barrier 140,discussed below, to the shelf 104. The hinge rail 322 is mounted to ashelf The clip 320, 360 mounts to the shelf through its interaction withhinge rail 322. The clip 320, 360 is further configured at an oppositeend to engage the wall 340, 350. More particularly, the clip 320includes a blade portion 324 that is configured to engage with the hingerail 322 and at any of the multiple positions along the hinge rail 322,thus providing flexibility in the placement of the clip 320. The bladeportion 324 may take on numerous shapes and configuration and may beconnected to or joined with a clip body 328. The clip body 328 isfurther connected to or joined with opposing wall mounting members 330.The wall mounting members 330 are configured to be positioned onopposing sides of a wall 340 with the wall passing between the mountingmembers 330. The wall mounting members 330 further define aligned holes332 for receiving a mounting fastener 334 that may be used to secure themounting members 330 to the wall 340, as depicted by FIG. 27. Thealigned holes 332 may be thru holes or threaded holes. As can beappreciated, any type of fastener or securement technique may be used tosecure the clip 320 to the wall 340.

Where a wall 340 or 350 is placed at the side end of a shelf, a clip 360can be used to further secure the wall 340, 350 to the shelf 104. At theedge of the shelf, the hinge rail ceases (not shown). Clip 360 includesa blade portion 362 that extends in only one direction from the clipbody 364. The blade portion 362 is configured to engage the hinge rail322. In an embodiment, the blade portion engages only a single hingepiece or knuckle of the hinge rail. For example, in FIG. 27, a singlehinge piece or knuckle is designated by 323. The blade portion 362includes a first blade portion 363 and a second portion 366 that can beat an angle to first portion 363. The second portion 366 can beconfigured to interact with the side 324 of knuckle 323. The blade 362may take on numerous shapes and configuration and may be connected to orjoined with a clip body 364. The clip body 364 is further connected toor joined with opposing wall mounting members 368. The wall mountingmembers 368 are configured to be positioned on opposing sides of a wall350 with the wall passing between the mounting members 368. The wallmounting members 368 further define aligned holes 370 for receiving amounting fastener (not shown) that may be used to secure the mountingmembers 368 to the wall 350. The aligned holes 370 may be thru holes orthreaded holes. As can be appreciated, any type of fastener orsecurement technique may be used to secure the clip 360 to the wall 340or 350.

A front retaining wall 116 may be positioned along the front edge of theshelf 104. The front retaining wall 116 can serve as a “fence” torestrain the product in the product lanes 112 and assist in preventingthe product from falling off the front of the shelf 104. The retainingwall 116 stops the forward movement of product that is caused by theurging of the pushers, described below. As exemplified by FIG. 6, theretaining wall 116 may be mounted to a channel or rail 118 that extendsalong the front edge 119 of the shelf 104. The channel or rail 118 maybe mounted to existing holes in a standard dealer shelf, or secured byany other known manner to the shelf 104. The retaining wall 116 may bemounted to or on the channel or rail 118. The front retaining wall 116may be made of a clear plastic to permit visualization of the product onthe shelf and provide a more aesthetically pleasing organization to themerchandised product. The front retaining wall 116 can also be createdfrom opaque or semi-transparent material, or from wire, and can beadaptable to display graphics. The front retaining wall 116 can have avariety of configurations, such as rectangular, oblong, repeatingpatterns or the like.

As more clearly shown in FIG. 7, the front retaining wall 116 may alsoinclude holes or openings 120 extending therethrough that are spacedalong the wall 116. The holes 120 permit the consumer and storepersonnel to push the product back and away from the retaining wall 116for ease of insertion and removal of the product.

As shown in FIGS. 1 and 2, the retaining wall 116 can have a height thatpermits the removal of a single product at a time or, depending on thedesired level of security, a couple of products or a few products at atime. In other words, the height of the retaining wall 116 can permitlimited access to and removal of product from the display system 100.Stated another way, the retaining wall 116 is not so tall as to prohibitany access to the product, but is sized to allow the consumer or storepersonnel to access and lift a limited number of product over theretaining wall 116 at one time. This limited removal of products isaccomplished through the use of the retaining wall 116 and the closeproximity of the shelf 104 positioned above the product. That is, in oneembodiment, the shelf 104 located above the product will be positionedin close proximity to the top edge of the product, or the top edge ofthe product divider 110, whichever is taller. The shelf 104 locatedabove the product, the product dividers 110, and the retaining wall 116will form an opening or window 131 through which only a single, two, orpossibly a few, product(s) can be removed at one time or in a singlemotion. This configuration also deters “sweeping” of product from theshelf 104. The size of the window 131 can be adjusted by adjusting thelocation of the shelf 104 above the product, the dividers 110, and/orthe retaining wall 116, or through the use of a second retaining wall122, barrier 130, and/or barrier 140, described below. This window 131adjustment permits flexibility with the system and allows the store toset the window 131 size depending on the product size and how manyproducts they want to permit consumers to remove at a time.

In an exemplary embodiment, if taller products are merchandised on theshelves 104, or if a smaller window 131 is desired, a second retainingwall 122 may be positioned behind or possibly in front of the retainingwall 116 to serve as a retainer for the product. As used herein, thesecond retaining wall 122 may be referred to as a “tab” and may includeany retaining structure or “fence” that can be selectively configured ormounted to the shelves 104 to provide selective theft prevention ofspecific products, such as high theft items. Consequently, the secondretaining wall or tab 122 may have many configurations, shapes anddesigns, and may be used in front of individual rows of product orgroups of rows of product.

As shown in FIGS. 6 and 7, the second retaining wall or tab 122 may bemounted to or on a second channel or rail 124 that extends parallel withthe channel or rail 118. The retaining wall or tab 122 may be slidablerelative to the shelf 104 or rail 124, or may be fixed relative to theshelf 104 or rail 124. The tab 122 can be positioned between adjacentdividers 110 and held in position between the dividers 110. In otherwords, the tab 122 may not be permitted much slidable movement in or onthe channel or rail 124 because the dividers 110 will hinder suchslidable movement. In some embodiment, the dividers 110 contain aportion that serves as a stop to prevent the tab or first retaining wallfrom moving laterally. Such configuration further prevents theft of theproduct as potential thieves will not be permitted to simply slide thetab 122 to the side and remove numerous products at a time.

The second retaining wall or tab 122 will have a height that permitsaccess to and removal of a limited number of product. If desired, thetab 122 may have a height that permits removal of only one product at atime. With the use of tabs 122, the display system 100 will haveflexibility in that tabs 122 of varying height may be positioned infront of the product lanes 112 to accommodate various sized products.That is, if a row of product has a product height that is different thana product in an adjacent row, tabs 122 of varying height can be used toprovide the proper level of security and access to the product.

In one embodiment, the tabs 122 may be sized to extend across oneproduct lane 112 or in front of a single row of product. In analternative embodiment, the tab 122 may be sized and shaped to extendacross multiple product lanes 112. In this embodiment, the tabs 122could include slots or channels to permit the tabs to “straddle” thedividers 110 and thereby extend across multiple product lanes. Inaddition, the dividers 110 could extend through the slots or channelsand thereby inhibit slidable movement of the tabs 122.

The second retaining wall or tab 122 may also be used in place of theretaining wall 116.

In other words, the front “fence” on a product facing may be the tabs122 of varying height, length and width, or of the same dimensions. Inthis configuration, the channel or rail 118 may be used to mountdealer-shelf accessories, such as clip-in signage, price tag holders,and the like. The tab 122 also can be attached to the divider 110 or canbe formed such that the tab 122 and divider 110 are an integral piece. Awall or partial wall structure such as tab 122 can exist at the front ofthe divider 110 and can extend to the left or right or to both the leftand right of the divider. This wall or partial wall can be used with orwithout a front retaining wall 116.

In an exemplary embodiment, the tabs 122 may include holes or openings125 through the tab 122, similar to the holes or openings 120 in theretaining wall 116, to permit the consumer and store personnel to pushthe product back and away from the retaining wall 116 and tab 122 forease of insertion and removal of the product. In other words, the holesor openings 126 allow product to be replaced by a consumer who removesit and decides not to purchase the product. To this end, the holes oropenings 120, 125 are constructed to allow finger access therethrough topush back the row of product. Once the products are pushed backward, theconsumer or store personnel can replace the removed products back intothe facing. It should be understood that tabs 122 also can be used thatdo not include the holes or openings 125.

In an exemplary embodiment, the tab 122 may provide securement for anindividual row of a product facing. That is, it may be desirable toprovide additional theft deterrence for an individual row of product. Inthis configuration, the tab 122 having the desired dimensions may bepositioned in front of a desired product row to provide additionalsecurement for just that row of product. This embodiment will providethe stores with additional flexibility with their planograms and productfacings in that individual tabs 122 of different dimensions may beplaced at various locations across the facing to enhance the securementof particular products.

In an embodiment, retainer tabs 122 can be used on an individual facingbasis for specific products. If a shelf is merchandised with productpackages of variable height, the retainer wall 116 must be of a heightthat allows the shortest product package to be lifted over it. If ashelf 104, barrier 130, or barrier 140 is employed above the product,then the shelf 104 or barriers 130, 140 must be located at a heightabove the product to allow the placement of the tallest product belowit. This may allow a thief easy access to the taller product by beingable to easily lift the taller product in quantity over the relativelyshort retainer wall 116. It can be desirable, then, to increase theheight of a front barrier only in front of the taller product. Thesecond retaining wall or tab 122 can be of a taller height than theretaining wall 116 and can be generally taller than required for thesmall product packages. The retainer wall or tab 122 can therefore beconstructed and used to limit access to the taller product and removalof several taller products at a time or in one motion, further securingproduct and deterring theft. Similarly, the retainer wall or tab 122 canbe constructed and used to limit access to smaller but deeper productsand to limit the removal of several smaller but deeper products at atime or in one motion. The retainer tab 122 thus allows flexibleplacement of product on a shelf by the retailer and manufacturer, nomatter the size, shape, and configuration of the product.

The retaining wall 116 and tab 122 may be mounted, directly orindirectly, to the shelf 104 using numerous techniques. The retainingwall 116 and tab 122 may be slidably mounted to or receivable in thechannels or rails 118, 124, which are secured to the front edge of theshelf through fasteners, adhesives, friction, tension, magnetism, orother restraining techniques and methods. The retaining wall 116 and tab122 may also be directly mounted or connected to the shelf 104 alsothrough the use of fasteners, adhesives, friction, tension, magnetism,or other restraining techniques and methods. The retaining wall 116 andtab 122 may be fixed to the shelf 104 or removably mounted to the shelf104 to permit additional flexibility in the design and level of securityof the system.

Pushers 126 may be placed behind product between the back wall 106 andthe front edge of the shelf 104 to push the product forward so that itmay be removed from the front of the shelf The retaining wall 116 andtabs 122, if used, in some embodiments can stop the forward movement ofproduct that is caused by the urging of the pushers. Known pushers maybe used with the invention, including the pushers and pusher systemsdescribed in U.S. Pat. No. 6,041,720 to Hardy, U.S. Pat. No. 4,830,201to Breslow, and International Application No. PCT/US02/15760 andcorresponding International Publication No. WO 02/091885 A1 to Hardy,all of which are incorporated herein by reference. The pushers 126 maybe spring-urged pushers that move along a track 128 to push producttoward the front edge of the shelf 104, as shown in FIG. 6. Track 128can form a floor on one side of the divider. A second floor, with orwithout a track, can be located on the other side of the divider.

In an embodiment, the pushers 126 may have a pusher face or paddle 129that may extend laterally to increase the pushing surface of the pusherto thereby pusher wider product more effectively. In other words, thepusher 126 may have an extendable pusher face to push either narrowproduct or wide product. The pusher face or paddle 129 may be extendablefrom a retracted position to one of several extended positions. Theextended pusher face locates the product pushing surface behind thecenter or near the center of the wider product, thereby greatlyenhancing the pushing leverage on the wider product. Numerous othertypes of pushers and pusher faces may be used with the invention,including the systems and pushers described in U.S. patent applicationSer. No. 10/772,134 to Hardy, which is incorporated herein by reference.

The pushers 126 may be stand-alone units that are mountable to the shelf104 using any known technique, including the channel mounting techniquedepicted in the figures. That is, in one embodiment, the pusher 126 maybe mounted to a front rail or channel 133, as shown in FIG. 6, and maybe slidably adjustable within or on that rail or channel. Alternatively,the pushers 126 may be used in conjunction with dividers 110 and may beoperatively mounted to the dividers 110, as disclosed in the abovereferenced patents and application, or as known in the art.

In another embodiment, the pushers 126 may incorporate springmechanisms, such as coil springs, that include an indicia strip. Theindicia strip is provided on spring mechanism and contains data relatingto the position of the pusher 126. A sensor assembly may scan theindicia strip and transmit data representative of the product and theposition of the pusher on the display system to a store computer or someother suitable device, such as a portable computer or controller. Thetransmitted data can be used to determine inventory levels and can bedone so in real time. With this embodiment, the amount of productremoved from a particular location in the store can be determined Thisinformation can be used to determine the effectiveness of productplacement and promotional displays, particularly when a product can beobtained from various places within the retail store. And with respectto deterring theft, a deviation in the typical purchasing habits of theconsumer can trigger an alarm. That is, the alarm can be used to alertsecurity personnel to the fact that too much product has been removedfrom the shelf at one time and thus a potential theft has occurred. Thelocation of the incident can also be used to alert a security camera soas to focus the camera in the direction of the potential theft, asdiscussed below. With this embodiment, numerous types of sensors anddetection techniques may be used to monitor the relative position andmovement of the pusher 126. For example, in an embodiment, the indiciastrip may contain numerous types of patterns that can be opticallyreadable or can be read using several different types of detectionmethods, such as passive variable capacitance, inductance, resistance,magnetics, or active signal detection. Numerous other types of sensorsand detection techniques are possible with the invention for detectingunusual movement of the pusher 126 that may be indicative of a potentialtheft situation, including the systems and techniques described in U.S.patent application Ser. No. 10/772,010 to Swafford et al., which isincorporated herein by reference.

In other exemplary embodiments, the merchandised product may be urgedtoward the front of the shelf 104 through other techniques, includingfriction, gravity and/or magnetism. Each of these techniques may be usedwith the display system 100 and the teachings of the present invention.These techniques may be used with or without dividers 110, depending onthe desired application. In one embodiment, the shelf is not completelyhorizontal but has an incline or decline from back to front.

In another embodiment, the merchandised product may be urged toward thefront of the shelf 104 through vibration or quick movements that orientproducts in a particular direction on the shelf 104. Vibration can causeproducts to move forward on the shelf 104 and prevent them from movingbackward so that the product is front facing. This vibration may beapplied through mechanical, electrical or other structures or designs.

In one embodiment, directed vibration moves product toward the front ofthe shelf The directed vibration causes product to move in particulardirections or in one direction and not to move in other directions.Through this vibration, which is instituted through the shelf 104,upright 102, floor, wall, ceiling or other structure, or through avibrative pulse or signal traveling through the air, the product movesin a particular direction, such as frontward.

In another embodiment of the vibration technique for urging productforward on the shelf 104, general undirected vibration is applied to thesystem. This vibration may be applied through the shelf 104, upright102, floor, wall, ceiling, other structure or through vibration or asignal traveling through the air. Directors, such as small toggles,ridges, flanges, fingers, or the like, cause product to move in aparticular direction depending on their configuration, shape, andorientation. These directors can channel the energy from unspecificvibration and force product in a particular direction, such asfrontward. The directors can be placed on the shelf 104, divider 110,floors, walls or ceilings of the system and can be incorporated into theproduct itself.

In an embodiment of the vibration technique, product sits on a floor andfriction moves product toward the front of the shelf In one embodiment,the floor may be a flat surface panel operatively coupled to a motionproviding device. In use, product is placed on the flat surface paneland a combination of gravity and friction hold the product in place onthe flat surface panel. The motion providing device then slowly movesthe flat surface panel toward the retaining wall 116 located at thefront of the shelf 104. After a preset amount of time, or throughproduct position sensing techniques, the motion providing devicequickly, in a jerking motion, pulls the flat surface panel in theopposite direction or, in other words, toward the back of the shelf Bydoing so, the quick motion of the flat surface panel breaks the bond offriction between the product and the flat surface panel causing the flatsurface panel to slide relative to the product and the product to remainat its location. The motion providing device will then repeat thepreviously described process and begin to slowly move the flat surfacepanel toward the retaining wall 116. Examples of such vibrationtechniques for urging product forward on a shelf are disclosed in U.S.patent application Ser. No. 60/541,859 to Hardy, which is incorporatedherein by reference.

As indicated above, the dividers 110, retaining wall 116 and tabs 122assist in preventing a thief from sweeping a number of products into hisor her coat or bag or from taking several products in the same facing.To even further limit the access to the product, in another exemplaryembodiment, a horizontal barrier 130 (FIG. 2) may be included above theproduct packages and secured to the front edge of the shelf 104positioned above the product. The barrier 130 may be fixed to the frontedge of the shelf 104 or may be fixed to uprights 102. The barrier 130further deters unobstructed access to the product in the product facingby reducing the area, window or opening through which product could beremoved from the shelf The barrier 130 may be constructed separate fromthe shelf or may be integral with the shelf The barrier 130 may span onerow of product on a facing, or may span multiple rows of product,depending on the desired level of security. Alternatively, the barrier130 may comprise another shelf 104 positioned just above the product. Inthis embodiment, the shelf 104 above the product is positioned in closeproximity to the product. The barrier 130 restricts access from thefront of the shelf 104 to only one or a few products positioned behindthe front product in a facing row to permit the removal of only a fewproducts from a shelf, or a product pusher, at one time or in onemotion. The retaining walls 116 and tabs 122 may be used conjunctivelywith the barrier 130 to prevent product from being easily removed fromthe shelf 104. In other words, the present invention contemplates theuse of one, two or multiple barriers or walls to prevent severalproducts from being removed from the shelf at a time or in one motion.The barrier 130 may be made of various materials and may be secured tothe front of the shelf 104 through any known technique.

A further embodiment of the invention incorporates a barrier 140 thatspans across one or two, some, all or the majority of the top of theproduct on a shelf 104. The barrier 140 functions similar to a door inthat it may be hinged or movably mounted to the edge of the shelf 104,or the barrier 130, just above the product to be protected. As usedherein, the term “barrier” is meant to include any structure that willprevent, inhibit or obstruct access to the product on the shelf 104. Thebarrier can embody numerous shapes and configurations. The barrier 140may be mounted to the shelf 104 using existing mounting holes on theshelf The barrier 140 also may be mounted on the front edge of a frontrail from the shelf above it. The front edge of the shelf can have hooksor “j” shapes on its underside. The barrier 140 can have apertures whichfit within the hooks or “j” shapes. The barrier 140 defines a bottom lipor edge that may meet or overlap the top edge of the retaining wall 116or tab 122. Such meeting or overlap further closes off access to theproduct except with deliberate action. In an exemplary embodiment, asshown in FIG. 13, the barrier 140 may include a handle 202 to assist inmoving the barrier 140 from a closed position to an open position, andvice versa. The handle may be molded with the barrier 140 along the edgeof the barrier as exemplified by FIG. 13, or the handle may be aseparate component attached, mounted, secured, or adhered to the barrier140 using any known technique. One skilled in the art will appreciatethat the invention is not limited by a particular shape or configurationof the handle and that the handle may define numerous shapes orconfigurations. Moreover, the barrier 140 may be configured with areinforcing rim that extends along the edge of the barrier 140. Thereinforcing rim provides additional structural integrity and rigidity tothe barrier 140. The reinforcing rim may also be equipped or configuredwith a handle. If the barrier 140 is configured with a locking mechanismas described herein the reinforcing rim will assist in preventing apotential thief from bending or breaking the barrier 140 and thus givingthe thief access to the product that is intended to be locked andsecured on the shelf.

A hole or opening 204 may be located in the barrier 140 through whichmay be mounted a cable lock or similar locking mechanism, as discussedbelow.

In an alternative embodiment, the product display system includesinverted features. The aspects of the invention that are placed on afloor or a shelf and extend upward can be placed on a ceiling or extenddownward, and vice versa. For example, the barrier 140 and retainingwall 116, the dividers 110, and tabs 122 may be inverted. It iscontemplated that in some embodiments the retaining wall 116, thedividers 110, and/or tabs 122 may be configured above the barrier 140which would extend upwardly from the shelf 104. The retaining wall 116,the dividers 110 and/or tabs 122 may be placed on the underside of theshelf above the product and extend downward. Pushers 126 and/or tracks128 can be secured to the underside of a shelf such that the pushersextend downward and the pusher springs are located near or behind theportion of the pusher that is near the underside of the shelf.

In some embodiments, to access product behind the barrier 140, thebarrier 140 must be moved or lifted, which requires a deliberatemovement and the use of one hand to hold the barrier 140 in place. Whilethe barrier 140 is lifted or moved, the product can be removed. Aconsumer or store personnel who uses one hand to hold the barrier 140 inplace, will need to use the other hand to remove product from thedisplay system 100. This embodiment is constructed to inhibit theability of a consumer to access product with two hands at the same time.While product is accessible to the consumer or store personnel, theremoval of large amounts of product in a short period of time isdeterred. The barrier 140 can be created from a clear, opaque orsemi-transparent material and may be hinged or slidable in a variety ofcommon ways.

Referring to FIGS. 11 and 12, an adjustable and removable barrierextension 206 may be configured with the barrier 140. The barrierextension 206 may be used to provide additional product security bycreating a larger barrier to prevent or limit access to the product onthe shelf The barrier extension 206 may be selectively mounted to thebarrier 140 through the use of mounting holes 208 and fasteners 210. Asshown in the figures, several mounting holes 208 can be located oneither the barrier 140 or the barrier extension 206 or both. Thesemounting holes can be aligned vertically or non-vertically. The severalmounting holes 208 permit the barrier extension 206 to be adjustedrelative to the barrier 140 to permit the barrier extension 206 toextend a desired distance, depending on the application, the desiredlevel of security, or the placement of the shelves. Other techniques formounting or attaching the barrier extension 206 to the barrier 140 arepossible with the invention, including techniques using other types offasteners or adhesives.

The barrier extension 206 can define numerous shapes and configurationsdepending on the desired application and level of product securement.For example, the barrier extension 206 can be configured to extendacross one row of product, one facing, or more than one row or facing.The barrier extension 206 may also be made of a clear, transparent, orsemi-transparent material to permit or prevent the product on the shelfto be visible to a consumer or stock person. The barrier extension 206may also include a handle similar to the handle 202 described above.

The barrier extension 206 may include a reinforcing rim 212 thatprovides additional structural integrity and rigidity to the barrierextension 206 to further provide additional product security. Thereinforcing rim 212 may also be equipped or configured with a handle214. If the barrier extension 206 is configured with a locking mechanismas described herein, or configured to be in a locked position, thereinforcing rim 212 will assist in preventing a potential thief frombending or breaking the barrier extension 206 and thus giving the thiefaccess to the product that is intended to be locked and secured on theshelf.

A locking mechanism may be further added to the barrier 140 to furtherhinder or prevent access to the product on the shelf In an exemplaryembodiment, as shown in FIG. 10, a cylinder lock 200 may be used tosecure and lock the barrier 140 or barrier extension 206 in a closedposition to prevent access to the product. The lock 200 may be mountedto the barrier 140 or barrier extension 206, through a opening or hole216 (FIG. 14), and may be configured to mount through the openings 120in the retaining wall 116.

In one embodiment, the lock 200 may engage an arcuate-shaped wallportion 117 configured in or formed with the retaining wall 116. Thearcuate-shaped wall portion 117 will further secure the lock 200 to theretaining wall 116 by permitting the locking tab of the cylindrical lock200 to more securely seat on, or be held in place relative to, theretaining wall 116. With the use of a lock, such as lock 200, a consumeror store personnel will need to use a key, special tool, or access cardto open the lock prior to moving or lifting the barrier 140.

In one embodiment, the lock 200 may engage an arcuate-shaped wallportion 117 configured in or formed with the retaining wall 116. Thearcuate-shaped wall portion 117 will further secure the lock 200 to theretaining wall 116 by permitting the locking tab of the cylindrical lock200 to more securely seat on, or be held in place relative to, theretaining wall 116. With the use of a lock, such as lock 200, a consumeror store personnel will need to use a key, special tool, or access cardto open the lock prior to moving or lifting the barrier 140.

Referring to FIGS. 18-20, another exemplary lock mechanism is depicted.A lock 280 may be a key-locked rotating oval-shaped lock. The lock 280is secured to the retaining wall 116 through a hole 282 formed in theretaining wall 116. More specifically, and referring to FIG. 20, thelock 280 includes an anchoring bolt that defines a bolt head 284. Thebolt head 284 and washer, if used, will secure the lock 280 to theretaining wall 116. As can be seen in FIG. 20, numerous holes 282 may bepositioned along the retaining wall 116 to provide flexibility in thelocation and placement of the lock 280, as well as providing for the useof numerous locks 280. The lock 280 also can include flanges 290, 292that interact with retaining wall 116.

Referring to FIGS. 18 and 19, the barrier 140, or barrier extension 206if used, defines an oval-shaped opening 286. Similar to the flexibilityprovided by the numerous holes 282, numerous openings 286 may be placedalong the barrier 140 or barrier extension 206 to provide the sameflexibility. As shown in FIG. 18, when the lock 280 is in a lockedposition, the opening 286 prevents the lock 280 from passing through theopening 286. As illustrated by FIG. 19, when the lock 280 is moved to anunlocked position through the use of a key 288, the oval-shaped lock 280will to pass through the oval-shaped opening 286 thus permitting theopening of the barrier 140 or barrier extension 206. With the use of thelock 280 and its mounting to the retaining wall 116, as opposed to alock mounted on the barrier 140 or barrier extension 206 and extendinginto the shelf, there will be no interference with product on the shelf,as may sometimes occur with the barrier-mounted locks. In addition, thelock 280 can, but need not, interact with the channels or rails 118, 124and can leave these channels or rails substantially free to receiveother objects such as a retaining wall or tab 122. As can beappreciated, the invention is not limited to the depicted oval-shapelock 280 and opening 286 as well as the illustrated placement of thelock and opening; rather, many various shaped keyed or keyless locks maybe used with similarly shaped openings formed in the barrier or barrierextension and placed in numerous locations and still achieve thebenefits of the invention.

Alternatively, FIGS. 21-24 depict an additional locking mechanism. Alock plate 302 can extend through an opening or slot 304 formed in theretaining wall 116 and through an opening 306 formed in the barrier 140or barrier extension 206. The lock plate 302 is configured to receivethe padlock 300. One or more of the openings or slots 304 may be formedin the retaining wall 116 at various positions along the retaining wallincluding the depicted positions between the holes or openings 120 inthe retaining wall 116. The openings or slots 304 are configured toreceive the lock plate 302 and to secure the lock plate 302 onto theretaining wall 116, as described below. While the openings or slots 304are depicted as vertical slots, other shapes and configurations of theopenings or slots 304 are possible with the invention. Padlock 300 maybe used to secure and lock the barrier 140 or barrier extension 206 in aclosed position to prevent access to the product. The padlock 300 may beany known keyed or keyless padlock and may be mounted to the barrier 140or barrier extension 206 through the use of a movable lock plate 302.

As can be appreciated, depending on the desired level of security, oneor more lock plates 302 may be used to secure and lock the barrier 140or barrier extension 206 in a closed position to prevent access to theproduct. The lock plates 302 are movable in that they can be positionedwithin any of the openings or slots 304 along the retaining wall 116.Being movable also permits the barrier 140 or barrier extension 206 tobe made in various widths to protect only those products on the shelfthat must be protected. In addition, the lock plate 302 need notinteract with the channels or rails 118, 124 and can leave thesechannels or rails substantially free to receive other objects such as aretaining wall or tab 122.

In an exemplary embodiment, the lock plate 302 may be made of anysuitable metal or plastic material and may define a nose 310 that willextend through the retaining wall 116 and barrier 140 or barrierextension 206, if used. The nose 310 further defines an opening or hole312 for receiving the padlock 300, as illustrated by FIG. 21. The nose310 also defines a notch or cut-away 314 that, when assembled, will seaton the bottom edge of the opening or slot 304, as shown in FIG. 24. Oncein this position, the notch or cut-away 314 will prevent the lock plate302 from being slid or pushed back out of the slot 304 and behind theretaining wall 116.

The nose 310 is connected to or formed with a back plate 316. The backplate 316 includes legs or retaining members 318 that, when assembled,will be positioned behind the retaining wall 116 and assist in holdingthe lock plate 302 on the retaining wall 116. The back plate 316 andretaining members 318 may take on numerous configurations that aid inholding the lock plate 302 to the retaining wall 116. The lock plate 302may be configured to not only extend through the retaining wall 116 andbarrier 140 or barrier extension 206, it may also extend through and beused with the tab 122.

One skilled in the art will appreciate that any known locking mechanismcan be used with the invention, including a cable lock that may bemounted with the hole 204 (FIG. 13), and any known key, special tool,access card, electronic, magnetic or wireless means (for keyless lockingmechanisms) can be used to open the locking mechanism.

As depicted in FIG. 8, an exemplary embodiment of the inventionincorporates a system that causes an alert to store or securitypersonnel that a potential theft situation exists. In one embodiment,lifting or moving the barrier 140 activates a mechanical or electronicalert device 142, generally depicted in the figures, that provides asignal, such as an audible, inaudible, infrared, radio-frequency,cellular, ultrasonic or electronic signal (including digital and analogsignals), or a combination of these signals. This alert signal may be asound, tone or voice annunciation that alerts store or securitypersonnel that the barrier 140 has been opened or has been opened for anunusually long period of time and potentially represents a theftsituation. The alert device 142 also may send an electronic or othersignal to play a voice message via the store paging system, to activatea local or remote strobe or annunciator light, or to send a signal to areceiver, such as a store computer, a pager, cellular device, or otherportable device carried by store or security personnel. The alert device142 may also activate a security video camera to monitor the particulararea or vicinity, or activate a monitor that is placed in the area orvicinity which would show the camera image to the consumers andpotential thief, or transmit the camera image to security or storemanagement via a web connection, cellular telephone, personal dataassistant, or any other signal receiving device. The alert device 142also may activate an advertisement, informational announcement or otherstatement or display that is provided through voice, video or video andvoice. This advertisement, announcement or statement can be directed tothe particular product or product type associated with product behindthe barrier that activates the alert device. The alert device can belocated such that barriers of a width of no more than one product facingwill activate the alert device when lifted.

As used herein, the term “alert device” is meant to include any deviceor component that may provide an alert, warning and/or signal concerninga condition, situation, and/or circumstance. The alert device 142 may behard-wired to the store's security system or may be a wireless system.Wireless systems, if used, provide increased flexibility in installationand can be readily installed in existing shelves without the need toinstall wires for either power or communication. In addition, the use ofa wireless system allows for the gradual installation of a system. Forexample, items of high value (and therefore suffering from an increasedlikelihood of being stolen) or items that tend to have significantvariations in customer demand can be monitored first. With a wirelesssystem, the alert signal may be sent to not only the store's securitysystem or computer, but also any portable device or receiver, such as acontroller, personal data assistant, pager or cellular telephone thatmay be carried by store personnel or security. Also with the wireless orwired system, the store's computer can process further the alert signalto determine whether a theft situation exists and can generate reportswhich can be analyzed to fine tune product placement, placement ofcameras, alert devices, sensors, and so forth, as well as fine tune thedelays and actions initiated by potential theft situations. Asunderstood by those skilled in the art the store's computer can beconfigured with the network server and can be accessible remotelythrough the world-wide web or other network, and can be controlledremotely through the world-wide web or other network.

In an exemplary embodiment, the alert device 142 is positioned on theshelf 104, either underneath, as depicted in FIG. 8, or on top of theshelf Existing mounting holes on the standard dealer shelf may be usedto secure the alert device to the shelf The alert device 142 may bepositioned near to or adjacent to the barrier 140. The alert device 142may be operatively connected to the barrier 140 through numeroustechniques. In one embodiment, the alert device 142 includes a switch144, such as a push-button switch, that will activate when the barrier140 is moved or opened. That is, as the barrier 140 moves and comes incontact with the switch 144, either directly or through the use of anactivator plate 145, the switch 144 is activated. Alternatively, in aclosed-barrier position, the switch 144 is pressed, as the barrier 140moves to an open position the barrier 140 moves away from the switch144, thereby releasing the switch 144 and thus activating the alertdevice 142.

The alert device 142 may be operatively connected or coupled to thebarrier to detect movement of the barrier through other methods ortechniques. For instance, a motion sensor or similar sensory devices,such as a light-emitting diode sensor assembly, may be used to detectmovement of the barrier and communicate that information to the alertdevice 142. The sensor may be mounted in a variety of locationsincluding on the barrier itself or next to the barrier to detect barriermovement. Alternatively, a magnetic switch may be incorporated to detectmovement of the barrier.

In another embodiment, as illustrated in FIGS. 102 through 107, thealert device 142 may be operatively connected or coupled to the barrier140 to detect movement of the barrier 140 through the use of apressurized pneumatic tube 1100. As shown in FIGS. 104 through 107, thepneumatic tubing 1100 may be located in an area or elongated space 1110between an edge 140A of the barrier 140 and the security rail 678. FIGS.104 and 105 illustrate one embodiment of the barrier 140 and pivoting ofthe barrier 140. FIGS. 106 and 107 illustrate another embodiment of thebarrier 140 and pivoting of the barrier 140. Generally, in thisembodiment, the pneumatic tubing 1100 may be in the form of plastic orcompressible tubing, such as surgical tubing, rubber tubing, or similarsuch product and/or material. The pneumatic tubing 1100 may be connectedto an air switch 1120 or pneumatic sensor/switch. The air switch 1120may include an internal diaphragm and/or metal contact as known and usedin the art to sense differences in air pressure. When the air switch1120 senses a difference in air pressure, the switch 1120 is capable ofsending a signal. The air switch 1120 may be operably connected to thealert device 142. In another embodiment without departing from theinvention, the air switch 1120 may act as the alert device 142.

As illustrated in FIGS. 102 through 107, the air switch 1120 activateswhen the barrier 140 is moved from the closed to the open position. Thatis, as the barrier 140 moves and the edge 140A of the barrier 140 pivotsand pinches or pushes on the pneumatic tubing 1100, the air switch 1120senses the difference in pressure and the switch 1120 is activated,thereby activating the alert device 142. Alternatively, the air switch1120 de-activates when the barrier 140 is moved from the open positionto the closed position. That is, as the barrier 140 returns to theclosed position and the edge 140A of the barrier 140 pivots away fromthe pneumatic tubing 1100, the air switch 1120 senses the return ofpressure and the air switch 1120 is de-activated, thereby de-activatingthe alert device 142.

The air switch 1120 and pneumatic tubing as described above andillustrated in FIGS. 102 through 107 may be used with any of the barrierand/or door configurations described in this invention. For example, theair switch 1120 and pneumatic tubing 1100 described above may be usedwith the low profile shelf system 600 as illustrated in FIGS. 60-73,identifying a pivotal barrier 640 and an alert device 650.Alternatively, the air switch 1120 and pneumatic tubing 1100 describedabove may be used with a merchandise system 1010 as illustrated in FIGS.92A through 101C, identifying a door assembly 1020 and an electroniccontrol unit 1080. Additioanlly, the alert device 142 may be operativelyconnected or coupled to the barrier to detect movement of the barrierthrough other pressure sensitive methods or techniques without departingfrom this invention.

The alert device 142 may include sensory components and time-delayfeatures that will calculate how long the barrier 140 has been moved oropened. Upon reaching a predetermined time period, in other words, asthe barrier 140 has been moved or opened for a certain duration, thealert device 142 will send a signal, such as the above-mentionedsignals, to alert the store personnel, security and/or the consumer thatthe barrier 140 has been opened or moved for a long period of time,thereby indicating a potential theft situation. In an exemplaryembodiment, upon the passing of the predetermined time period, the alertdevice 142 may send an audio alert signal, including a signal differentfrom a previous audio alert signal, that would draw attention to thevicinity. The alert device 142 can therefore be designed to provide itsalert for a fixed period of time before becoming silent.

In another embodiment of the alert device 142, the audio alert signal isadjustable to provide a variety of alert tones of varying frequencies,or to announce that the barrier 140 has been opened or moved for toolong and that the consumer needs to close the barrier 140, or to send asilent alarm to the store and/or security personnel. Different signalsor frequencies can be used as the length of time in which the barrierhas been opened or moved increases. Numerous combinations of alertsignals are possible with the alert device 142 depending on the desiredlevel of security. The alert signal is adjustable and numerouscombinations of signals may be used to provide the desired signal leveland thus security level, yet avoid turning away legitimate consumersfrom selecting and purchasing the product. That is, for example, thealert device 142 can be programmed to provide an alert signal that willdraw the attention of surrounding shoppers or store/security personnel,yet short enough to limit aggravation of the legitimate consumers orstock person.

Also, in another embodiment, a two-tiered response could be implemented.For example, if the barrier 140 is moved, a signal could be transmitteddirectly to the security camera, or via the store computer or both. Inaddition, an inaudible notification could be provided directly tosecurity personnel. If the barrier 140 remains open or moved for a setperiod of time, more clearly indicating a potential theft, an additionalaudible alarm and flashing lights could also be activated, or any otheralarm. Thus, the response could be configured to more carefully matchthe situation.

Referring to FIG. 15, in an exemplary embodiment, a security videocamera 260 may be placed in the vicinity of product that are high risktheft items, or other product of concern. As shown in FIG. 16, a monitor262 also may be placed in the vicinity of the high risk product. Themonitor 262 may be used to show the security camera image to consumersand any potential thief. Thus, a consumer or potential thief thatremoves product from the shelf 104 of the display system 100 may realizethat their actions are being watched by a camera and potentiallyrecorded.

As can be appreciated, the position of the potential theft relative tothe security camera 260 would be beneficial to provide an instruction tothe security camera to focus on a particular position. This positionalinformation could be generated by a number of methods, includingproviding a store computer with the security camera coordinate systemfor the security camera. The location of the alert device 142 relativeto the security camera could be determined during setup and during apotential theft situation; the location of the alert device 142 could beused to direct the focus of the security camera. Alternatively, thesecurity camera could be configured to focus in several positions, suchas three points along an aisle, and the store computer could indicatewhich position was the most appropriate for the particular situation.One skilled in the art will appreciate that the described methods areillustrative because of the numerous methods of controlling the securitycamera that exist.

In addition to the value of such system in loss prevention, the monitorcan show video in the form of advertising or consumer information. Asillustrated by FIG. 17, the monitor 262 can switch between theadvertising or consumer information and the camera image through the useof a video switch 264. This switching activity can occur on a periodicbasis, such as every 30 seconds, or can occur when predeterminedconditions are met, such as the lifting of the barrier 140, the removalof product, the movement of a pusher, or input from a proximity sensorthat a consumer has entered or approaches the area. By playing the videosegment, the device not only reduces loss, but becomes a source ofrevenue when advertisers are charged to place their message on thesystem.

A secondary video source for the monitor on which advertising, consumerinformation or other content is shown can be a video player 266 such asa video cassette recorder, compact disk-video player, solid statedigital video player, direct video, audio feed or other video sources.With respect to the switch 264, the switching action between the cameraimage and advertising or other content can be effected by a hardwaretimer or a small microcontroller. In one embodiment, the secondary videosource can contain a multitude of short video segments which arerandomly or non-randomly selected by the timer or microcontroller. Thecamera 260 may be a small, stand-alone type, not connected to any partof an existing security system, or it may be any typical store securitycamera existing in the store's security network. The monitor 262 may bea small flat, color, LCD type monitor and can be placed at numerouslocations on or near the shelf 104. For instance, the monitor may beplaced in overhead signage above the merchandised product or it can beattached to the shelf 104 edge. In some applications, a larger monitor,such as a CRT-type, plasma, LCD or projection monitor can be used. Apreferred solid-state digital video player may comprise the secondaryvideo source. The source may be housed in the same enclosure as themonitor or may be located remotely from the monitor.

Referring back to FIGS. 4 and 5, in another exemplary embodiment, theshelf 104 on which the product rests may be a “pull-out” shelf The“pull-out” shelf allows store associates or personnel access to theproduct to restock the shelf but prevents a thief from obtaining suchaccess. The pull-out shelf allows easy access to all products on theshelf This function, however, requires that the shelf not be movable bythe consumer or thief and therefore the pull-out function must beprotected by a key-lock, special tool, or other locking mechanism. Inthis embodiment, the product dividers 110 may be designed to be at leastequal to the height of the tallest product package on the shelf As theshelf 104 is pulled out, the product lane or dividers may cause thebarrier 140 to rise. If the height of the dividers 110 is lower than thetallest product package, pushing the shelf back in may cause the barrier140 to catch on the product packages and make it more difficult toreturn to its closed position. Additionally, pulling out the shelf 104will raise the barrier 140 which may activate an annunciator or signalgenerator, as explained above.

Referring to FIG. 9, in an exemplary embodiment, a barrier placed on atop-most shelf 104 may include a lock-box 108 that may be used forstorage of overstock product or additional display system 100components. In an embodiment in which the top-most shelf 104 is apull-out type, the shelf 104 will pull out while the horizontal barrierabove it remains in place, allowing product to be easily accessed. Asindicated above, the lock-box 108 may also be mounted to the verticaluprights 102, through known mounting techniques, and may be mounted atany location on the display system 100. The lock-box 108 may use anyknown locking mechanism that permits key or key-less entry to thelock-box 108. One skilled in the art will appreciate that other securitycomponents may be mounted to the lock-box 108 including the securitycamera, monitor, and alert device 142, to name a few.

In an embodiment, a stationary shroud 180 may placed toward the top ofthe product display system 100. The shroud 180 provides security andgraphic placement, and product may be stored within it. The shroud 180provides security in that it functions as a top wall or barrierpreventing access to the product from a point above the product. Theshroud 180 may mount on or to an existing shelf The shroud 180 may befixed or adjustable. With an adjustable shroud, the shroud can bepositioned at numerous locations on the product display system. Inaddition, the shroud 180 can be a pull-out shroud functioning in mannersimilar to the exemplary pull-out shelf 104 described above. Moreover,the shroud 180 can also serve as a shelf to hold product. In otherwords, the product display system 100 could include multiple shrouds 180that function as shelves to hold or display product. Also, the shroudcan be configured to mount the barriers 130, 140, through numerous knownmounting techniques. In an exemplary embodiment, the lock box 108 havinga lockable door 109, as shown in FIG. 9, may be placed on the shroud 180for additional product storage and graphic placement.

The product display system 100 of the invention offers various levels ofsecurement and theft protection. Each level described herein can be usedseparately and various or all levels can be used in conjunction witheach other. Each level can also be added to or adapted with existingshelf systems or be provided as a stand alone system. The divider orretaining walls 110 provide securement. The front retaining wall 116 or“fence” provides securement, with or without the retaining tabs 120. Thebarriers and access doors 130, 140 over the top of the retaining wall116 provides securement. The close positioning of the shelf 104 over theproduct located on the shelf below provides securement. The audible orother signal that is generated by the alert device 142 when the barrier140 has been open for a set period of time provides securement. Thesecurity camera and video and display devices provide securement. Eachof these separable aspects of an embodiment of the invention can be usedon its own in a retail setting, or can be used in conjunction with otheraspects of the embodiment. Each separable aspect can be added toexisting shelving or display systems to effectively retrofit and add oneor more levels of security to such existing systems.

One embodiment of the invention features various levels of theftdeterrent. One level assists in preventing sweeping of products. Pushers126, dividers 110, and retaining walls 116 are coupled with a shelf 104or barrier 130, or both, above the product to provide securement to theproduct. The pushers, dividers, retaining walls, shelf, and barrierallow approximately one, two or three packages to be removed through anopening at one time from a facing of the display system. Secondretaining walls or tabs 122 may be used to provide individual securementfor specific rows of product. The front wall 116 and tabs 122 may alsoinclude holes or openings that extend therethrough that would requirethe consumer to push on the product through the holes or openings inorder to remove the product from the shelf.

A second level of securement incorporates all of the features of firstlevel with the addition of a barrier 140 or access door. To access theproduct, the consumer must utilize two hands, one to lift or slide thebarrier 140 and the other to remove the product, thus adding a secondlayer of deterrent to the system.

A third level of securement builds upon the features of the first andsecond levels with the addition of a theft-warning notification device,such as an alert device 142, or other signal transmission device. Thealert notification or signal transmission is activated if the barrier140 or access door is open a predetermined amount of time. This delaycan be adjusted to any duration or eliminated. The notification providesan audible, inaudible, infrared, radio-frequency, electronic, orcellular signal that notifies consumers and/or store and securitypersonnel that the barrier 140 has been open for a particular period oftime. The signal transmission can send a signal to a store computer,store personnel or a security camera or monitor. The signal can alertthe store computer or personnel that the barrier 140 or access door hasbeen opened for a particular period of time and can activate thesecurity camera and monitor to show the thief an image of himself orherself in front of the product. This image can be recorded. Additionalalert notifications or signal transmissions can be activated as theamount of time the barrier or access door is open increases.

An additional level of deterrence of theft by consumers or storepersonnel is the use of a locking mechanism on the shelf 104 to limitunauthorized personnel from pulling out the shelf The system can requirethe use of a key or an uncommonly or commonly shaped instrument to beinserted into a concealed access slot in the front or underside of theshelf This method is designed to require someone with specific knowledgeof the shelf operation to disengage the lock. In an embodiment, thebarrier 140 or access door on the shelf 104 can be automatically raisedfor restocking purposes when the shelf is pulled out, then re-engagedonce the shelf has been returned to the closed position. In thisapplication, an audio alert may be incorporated that indicates that theshelf is being restocked with product.

In addition, in an embodiment, a stationary shroud 180 may be placedtoward the top of the product display and management system. The shroudprovides security by inhibiting access to the product from above theproduct. Also, a lock box can be placed anywhere on the system to storeadditional product that will be secured by a key lock or some otherlocking mechanism.

In one embodiment of the present invention, various aspects of theinvention are added to portions of existing shelves. In someenvironments, there are only one, two or a few potential high-theftproducts among a display of many products. Aspects of the presentinvention can be added solely to the portion of a shelf management anddisplay system with respect to those high-theft products. For example, abarrier 140 could be placed solely over those products. In addition,side walls could be placed to cover one or more of the sides of theproducts to further deter sweeping or other theft. A front barrier, alocking mechanism or other aspects of the invention described hereincould be used solely with the high-theft products or other highlyrelevant products in a display and not used with other products in thesame display. In one embodiment, a particular set of relevant productscan be effectively segregated from the other products within the samedisplay. This particular set of relevant products can be subject toadditional security aspects described herein that are not used with theremaining products in the display.

Referring to FIGS. 28-29, there is depicted an adjustable power bar 400that may be selectively mounted to the back wall 106. The power bar 400will provide electrical power to various components mounted to theshelves, including any video monitors, security cameras, lighting,illuminated signage, overhead header lights, radios, stereos, or anyother components that may be mounted to a shelf or the product displayand require electrical power. As illustrated by the Figures, the powerbar 400 is selectively adjustable between several positions toaccommodate shelf height changes or adjustments without causingobstruction with the mounting or adjustment of the shelf

Conventionally, power outlets were mounted to the shelf and were noteasily movable.

In fact, significant force was required to unlock the power outlets fromthe track on which they were mounted to then move the power outlets. Inother known applications, the power outlets were mounted to conductivetracks, similar to track-lighting tracks which included embedded powertracks. With those track-type systems, the power outlets needed to beplaced at correct locations and snap-fit into position. Once installed,the power outlets were not slidable.

The power bar 400 of the invention solves these problems and other knownproblems by providing a power source for a product display that iseasily mountable to the display, such as the back wall 106, and iseasily adjustable to accommodate changes made to the positions of theshelves. The power bar 400 includes an elongated body 402 that may beattached to the back wall 106 of the display. As illustrated, the powerbar 400 may be mounted in a vertical manner and the elongated body 402may extend the entire height of the product display or alternativelyless than the entire height of the product display. The power bar 400may be slidably moved (as indicated by direction arrow 401) a sufficientdistance to avoid interference with the product shelf that may be placedat approximately the same vertical height, or with the repositioning ofthe mounted product shelf The power bar 400 includes one or more poweroutlets 404 that may be configured at numerous positions on the powerbar 400. Once in the desired position, a fastener, not shown, may bepositioned through an adjustment slot 406 to secure the power bar 400 tothe back wall 106 at the desired height. The adjustment slot 406 iselongated to permit further adjustment of the power bar 400.

The elongated body 402 defines an elongated hollow cavity 408 throughwhich may pass conducting wires 410 that are used to supply the power tothe power bar outlets 404. The elongated body 402 may also include arecessed channel 412 formed in the body 402 and along each side of thebody 402. The channel 412 may be used as a receptor for receiving andaligning the power bar 400 onto the body 402. The power bar 400 may fiton or within the channel 412 in a tongue-and-groove manner, or any othersuitable mounting connection that permits slidable movement of onecomponent relative to another. Once installed, the power bar 400 willslide relative to the body 402 in or on the channel 412.

FIGS. 34-59 illustrate an embodiment of a box-shelf that may be secureddirectly to an upright. Thus, as depicted, the box-shelf may be providedas a complete unit that provides theft-prevention benefits as discussedabove while allowing for more straightforward installation in a retaillocation. As can be appreciated, in an embodiment the box-shelf may beconfigured to be self-contained so as to eliminate the need for asupport shelf.

Looking first at FIGS. 34-36, a box-shelf 3405 includes a top 3420 andtwo sides 3422 that can be connected together to form part of a housing3408. A recessed portion 3421 is provided so that in the event that thebox-shelf 3405 is mounted under a shelf, the recessed portion 3421 willaid in ensuring there is no interference with the brackets that supportthe shelf or other structure that may extend downward (not shown). Oneor more shelf supports 3430 are mounted to the box shelf 3405 so as toenable the box shelf 3405 to be mounted to a vertical support (notshown) in a traditional manner.

A slidable shelf 3410 is mounted to one or more tracks 3416, which canbe supported at least in part by the sides 3422. As depicted, theslidable shelf 3410 can include a support surface 3412 that supports adivider 3418 (which may be a pusher or a simple divider) and includes arail 3445 mounted to the front of the shelf 3410. The rail in turnsupports a retainer 3414.

As depicted, a door 3424 with one or more handles 3426 can be mounted tothe top 3420 via hinge system 4010 and is coupled to a control unit 3515that may be configured to produce an audible tone (immediately or aftersome predetermined delay) when the door is opened and may further beconfigured to provide a signal to a remote device so as to trigger videocapture or security personal.

Slidable shelf 3410 translates via a track 3416 when locking feature3525 is actuated. As can be appreciated, to translate the slidable shelf3410, the door 3424 needs to be opened and in an embodiment, asdepicted, the door may open up to 90 degrees. As can be appreciated, therail 3445 can also be mounted on the top 3420 of the box shelf 3405.

It should be noted that details such as discussed above with respect toFIGS. 1-33 may also be incorporated into the embodiment depicted inFIGS. 34-59, where appropriate. Thus, where desirable and/or convenient,the above details may be incorporated.

FIGS. 37A-37B show the locking feature 3525 in a locked or blockingposition and an opening and non-blocking position. In an embodiment, anopening in the lip 3547 allows a key to be inserted so as to translatethe locking feature 3525 from the locked to the open position. Thus, ascan now be appreciated, the locking feature 3525 is shown in both theblocked and open position in a number of the Figures.

As depicted in FIG. 38, one or more box shelves 34-5 may be mounted ontop of each other. In such a configuration, a path 3810 can allow theinsertion of a key (not shown) to actuate the locking feature 3525.

As can be appreciated from FIG. 39, the door 3424 can be pivotallymounted to support 3925. Furthermore, a hat channel 3915 can be providedfor additional strength and rigidity of the box shelf 3405. The hatchannel 3915 may also be used to support the locking feature 3525 and/orone or more tracks 3416. As depicted, two shelf supports 3430 (sometimesreferred to as brackets) are mounted to a rear panel 3940 and includeslots so as to allow the box shelf to be mounted to vertical supports inan adjustable manner even if the position of the vertical supportsinclude some degree of tolerance stack-up. The shelf supports 3430 canbe connected to one or more vertical rails (not shown) of a shelvingstructure.

FIGS. 40-47 illustrate additional details of the depicted embodiment ofthe box shelf. It should be noted that the box-shelf may be constructedout of known materials, such as powder coated 18 gauge steel or someother appropriate material. FIG. 48 illustrates an embodiment of thesupport surface 3412 and includes reference to cross-sections J-J andP-P. As can be appreciated from FIGS. 49-51, the lip 3547 can include ablocking lip 4910 in the center of the shelf (or in some other locationaligned with the locking feature 3525) but the blocking lip may not berequired in other locations, thus allowing (but not requiring) areduction in the amount of material used to make the support surface3412.

FIGS. 52-54 illustrate details one embodiment of the locking feature3525. FIG. 52 shows the hinge plate 5215 both in a partially explodedview and in an installed position. As depicted, the hinge plate 5215 ismounted to hinge base plate 5225 by a fastener 5230 that couples to anut 5240. A biasing element 5235 directs the hinge plate 5215 toward afirst or locked position. Thus, hinge plate 5215 a is a locked positionand hinge plate 5215 b is an open position. As can be appreciated,however, numerous other methods of mounting the hinge plate 5215 to thehinge base plate 5235 are possible.

FIGS. 54-59 illustrate additional details regarding embodiments of thelocking feature 3525, shelf support 3430 and other potential elements ofthe box shelf 3405. In addition, FIG. 59 depicts section H-H, from whichFIG. 46 is taken. It should be noted that any dimensional references aremerely exemplary and are not intended to reflect any limitations to thepresent invention unless otherwise noted.

FIGS. 60-73 illustrate another aspect of the invention, namely a lowprofile shelf system that improves the merchandising of product. The lowprofile shelf system improves product merchandising by creating morespacing between shelves to accommodate larger product. In some stores,there are large product sections wherein product management systems,such as those described above, are not the most ideal systems to usebecause there is not sufficient height (i.e., spacing) between shelvesto add such a system. In these instances, the product is merchandised sotightly between shelves that adding a product management system, such asthose described above, raises the product such that it may interferewith the shelf above. Occasionally, retailers are not willing to adjustthe shelves to incorporate a product management system because suchshelf adjustments typically must be done in fixed increments (e.g., oneinch increments), and moving shelves by such increments can sometimeslead to the undesirable eliminating of a shelf, such as the top shelf.

As depicted in FIGS. 60-73, the invention solves this problem by usinglow-profile shelf supports 600. Each low-profile shelf support 600 maydefine a back portion 602 and a front portion 604. The back portion 602may include a fastening plate 606 attached thereto (FIG. 72), eachfastening plate 606 having at least one hook formation 610 that can beinserted into a slotted upright (not shown). The fastening plate 606 maybe fastened to the shelf support through the use of fasteners 623.Alternatively, the back portion 602 may form the at least one hookformation 610 (FIG. 60). As shown in FIG. 60, the back portion 602 ofthe shelf support 600 may have a thickness that is substantially greaterthan the thickness of the front portion, resulting in the front portion604 having a significantly lower profile than the back portion of theshelf support 600. This reduced profile of the front portion results ingreater clearance between product shelves to accommodate larger productand/or the installation of the product management systems describedherein. In one embodiment, the thickness of the back portion 602 may be75% greater than the thickness of the front portion 604. Otherthicknesses of the front and back portions are possible to create thedesired low profile shelf support configuration.

Referring to FIGS. 61 and 73, the shelf supports 600 may be positionedbeneath and secured to a shelf 614. A pusher system 616 may be mountedto the shelf 614. The pusher system may include a pusher track 618 and apusher 620. Any of the pusher systems described herein may be used withthe low profile shelf supports 600. Additionally, a product divider 625may be mounted to the shelf 614 or made part of the pusher system 616,as described herein.

Referring to FIGS. 60, 63 and 64, a pivotable barrier 640 and a frontproduct retaining wall 642 may be mounted to a front rail 644, which maybe mounted to the front of the shelf 614. The front rail 644 may includeone or more channels 645 for receiving one or more retaining walls 642or signage identifying the products being merchandised. The front rail644 may also be configured to receive the pusher system 610 in either aslidable or non-slidable manner. The barrier 640 may be configuredsimilar to the barriers described herein. Similarly, the retaining wall642 may be configured similar to the retaining walls also describedherein.

Referring to FIGS. 62-65, an alert device 650 may be mounted to theshelf 614 at or near the back portion 602. Similar to alert device 142,the alert device 650 may be used to detect when the pivotable barrier640 is moved or opened and send an appropriate alert signal, asillustrated above. With this embodiment, the alert device 650 mayinclude a switch 652 that is activated by a linkage 654 that operativelycontacts the pivotable barrier 640 (FIG. 64). The linkage 654 may be ametal or plastic rod or flat stock of a suitable material. With thisembodiment, the barrier 640 may include a cam-shaped end 641 mountableto the front rail 644, as shown in FIG. 64, the cam-shaped end 641configured to contact and cause movement of the linkage 654 when thebarrier 640 pivots. The linkage 654 in turn may contact the switch 652of the alert device 650 (as shown in FIG. 65) to activate the alertdevice 650, which will send or emit the desired alert signal. A linkagecover 662 may be mounted over the linkage 654 to cover and protect thelinkage 654.

Referring to FIGS. 66-69, a security box-shelf 670 may be secured to thelow-profile shelf support 600 (or to the vertical uprights) and over thepusher system 610. The box-shelf 670 may be provided as a complete unitthat provides theft-prevention benefits as discussed above and may beconfigured to be self-contained so as to eliminate the need for asupport shelf The box-shelf 670 may include a top 672 that may be madeof clear material to permit products to be seen in the box-shelf 670.The box-shelf 670 may also include two sides 674 and a back wall 676that may be joined together to form the box-shelf 670. A front securityrail 678 may be mounted to the top 672 (as shown in FIG. 69). Thesecurity rail 678 may also be configured to receive a pivotable barrier640. The barrier 640 may be similar to the barriers described above andmay be opened to permit access to the products merchandised within thebox-shelf 670. An alert device may also be operatively coupled to thebarrier 640.

Referring to FIGS. 70-71, optional signage 690 may be mounted to theshelf 614 that is supported by the low profile shelf supports 600. Oneor more signage supports 692 may be used to support the signage 690. Thesupports may be mounted to one or more horizontal mounting brackets 694for added stability of the signage 690.

Referring to FIGS. 72-73, it should be understood that multiple lowprofile shelf supports 600 may be positioned underneath the shelf 614,depending on the size and configuration of the shelf. It should furtherbe understood that multiple pusher systems 616 and dividers 625 may bepositioned on the shelf 614 to merchandise multiple rows of product onthe shelf.

FIGS. 79-91 illustrate another aspect of the invention, namely amerchandise system 810. Similar to the other embodiments, themerchandise system 810 improves product merchandising by limiting thenumber and the frequency with which product can be removed from, forexample, a merchandising shelf by using various methods such as slowingthe rate at which product can be pushed towards the front edge of amerchandising shelf.

Referring to FIGS. 79-84, in an exemplary embodiment, merchandise system810 includes a base 812. The base 812 defines a generally flat planarsurface that may be configured to engage with or mount onto any knownshelf used in a store, as well as any other merchandise system 810, andin any known mounting configuration and orientation. The base 812defines a front edge 826, a back edge 828, a first side edge 820, asecond side edge 822, and one or more tracks 814. As is furtherillustrated, a housing 850 can be mounted to the base 812 in any knownmounting configuration and orientation. The housing 850 defines a topwall 852, a first side wall 854, a second side wall 856, and a frontretaining wall 876. First and second side walls 854 and 856,respectively, can be used such that when more than one merchandisesystem 810 is placed adjacent to another like merchandise system 810 ona shelf or stacked on top of another like merchandise system 810,product resting on the base 812 of each respective merchandise system810 remains separated or divided. In an embodiment, one merchandisesystem 810 can be stacked on top of another merchandise system 810without need of a separate shelf between the two merchandise systems.

In an exemplary embodiment, front retaining wall 876 is mounted at anangle, (for example, approximately a 45° angle) relative to the base 812and extends from the second side edge 822 to first side edge 820 towardsthe front edge 826. Angles other than approximately 45° are possible,including angles of approximately 15°, 30°, 60° and 75°, to name a few.Front retaining wall 876 can define a channel 888 located proximate thebase 812. Channel 888 further can define a detent 886. Front retainingwall 876 and first side wall 854 define an opening 878 through which, aswill be explained below, product can be removed by a customer oremployee. In an embodiment, front retaining wall 876 does not fullyextend from the second side edge 822 to first side edge 820. A lever 880can be operatively coupled to the merchandise system 810 for ejectingproduct through the opening 878. In an exemplary embodiment, lever 880is slidably mounted within the channel 888. The lever 880 can include alever biasing element 882 and a lever hook 884 adapted to move product.As illustrated, lever biasing element 882 can be a coil springpositioned between lever hook 884 and detent 886. The one or more tracks814 extend along the base 812 from the back edge 828 to the frontretaining wall 876. As shown, a track 814 can be used with a pusher 816.It should be understood that more or less than two tracks could be usedwith the invention, depending on the particular application. The base812 further defines a rack aperture 988 for use with a rack 986 as willbe discussed below.

Referring to FIGS. 88 and 89, in an exemplary embodiment, the one ormore tracks 814 extend longitudinally along the length of the base 812and define at least one rail 830 and an elongated aperture or channel832 in the base 812. The aperture 832 and rail 830 are sized and shapedto receive and mount a mating element of the pusher 816. The pusher 816is slidably mounted to the base 812 such that the pusher 816 does notlift out of the track 814. The present invention contemplates the use ofother shapes of rails and apertures to mount the pusher 816 to the base812. Other pusher mounting techniques are possible with the invention.

The pusher 816 also contains at least one pusher urging element 860 usedto urge the pusher 816 toward the front of the shelf The pusher urgingelement 860 may be any biasing element including, without limitation, aflat coil spring. The present invention may use one or more pusherurging elements 860 to urge the pusher 816 depending on the desiredapplication. The pusher urging element 860 may be mounted to the pusher816 and the base 812 using any known mounting technique. In theexemplary embodiment, one end of the pusher urging element 860 issecured to the base 812 near the front edge 826 of the base 812, and theopposing end of the pusher urging element 860 is positioned behind thepusher 816 to urge the pusher 816 toward the front of the shelf Further,pusher 816 includes an angled pusher face 892. In an exemplaryembodiment, angled pusher face 892 is positioned such that its anglerelative to the base 812 corresponds to the angle of front retainingwall 876. It should be understood, however, that angled pusher face 892can be positioned at other angles and can have various dimensions andshapes.

Referring to an embodiment of the invention in FIGS. 85 and 86, pusher816 will urge the product toward the front retaining wall 876. Whenproduct is positioned between the front retaining wall 876 and pusher816, only a single product can be accessed by customers or employeesbecause the opening 878 is equal in dimension to less than the width oftwo products. In an embodiment, the opening 878 is no more thanapproximately 50% wider that the width of a single product. In anotherembodiment the opening 878 is roughly the width of a single product yetwide enough to allow a single product to pass through the opening 878.The positioning and dimensions of opening 878, in combination with thepositive pressure the pusher 816 places on product against the frontretaining wall 876, hampers a customer or employee's ability to removeproducts using solely digits (i.e., fingers) or digital force. Tofacilitate the removal of a single product, when product is positionedbetween the front retaining wall 876 and pusher 816, a force can beapplied to lever 880 such that lever 880 can be slidably translated. Aslever 880 is slidably translated, lever hook 884 engages the mostforward positioned product. When the customer or employee slidablytranslates lever 880 to a fully extended position, the single product ispartially ejected from the housing 850 and can be easily removed by thecustomer or employee. Further, when lever 880 is in a fully extendedposition, lever biasing element 882 is compressed between lever hook 884and detent 886. Accordingly, when a customer or employee stops applyingforce to the lever 880, lever biasing element 882 biases lever 880 backinto its original position.

In the embodiment described below, when customers or employees reach andpull out the product available to them, the pusher 816 is slowly urgedtoward the front retaining wall 876 by pusher urging element 860 and,after a pre-determined period of time, a single product once again ispositively pressured between the pusher 816 and the front retaining wall876 such that the product is adjacent opening 878. An attempt by acustomer or employee to remove or urge the next product forward after afirst product is removed is hampered because the product is positionedat an angle corresponding to angled pusher face 892 and thus, if acustomer or employee attempts to tip the product forward, the productwill be biased in a standing position by the second side wall 856. Thespeed at which the pusher moves can be controlled by various devicesincluding, without limitation, a dampened gear assembly discussed below.By providing a merchandise system that urges product forward at a slowrate of speed, a customer or employee can be inhibited from removingmore than one product at a time and is assisted in removing product onlyonce every pre-determined amount of time.

In an embodiment of the invention, to provide the desired slow rate ofspeed for the pusher 816, an exemplary dampened gear assembly 980 may bemounted to the pusher 816. The dampened gear assembly 980 may include agear 982 and a gear housing 984 that can be filled with any dampeningfluid known in the art. A portion of gear 982 is housed within gearhousing 984. A rack 986 can be mounted to rack aperture 988. The rack986 defines a plurality of teeth 990. Gear 982 of gear assembly 980 isadapted to engage the plurality of teeth 990 of rack 986. In operation,when product is removed from the base 812, and pusher 816 is urgedforward by pusher urging element 860, gear assembly 980 acts to slow therate at which pusher 816 is urged forward. This can be accomplishedbecause rotation of gear 982 is regulated by the dampening fluid locatedin gear housing 984 which acts to resist movement of the gear 982 withingear housing 984. Again, other dampening techniques may be used with thepresent invention to affect the desired slow rate of movement of thepusher toward the front of the shelf

In an embodiment, front retaining wall 876 is made of a clear ortransparent material that allows for the product to be viewed throughfront retaining wall 876. In an embodiment, front retaining wall 876enables advertisements or marketing materials to be placed on frontretaining wall 876. Base 812 also can include a display area 999 (seeFIG. 79) for advertising or marketing material as well as productinformation such as product pricing information. Because display area999 can include product information, merchandise system 810 can be, aswas discussed above, stacked on top of another like merchandise system810 without the use of shelves.

In an embodiment, a locking device (not shown) can be used to preventthe removal of product. Such locking device may include a rotatablebarrier, a door, or a locking clip. The locking device, for instance,could prevent product from fitting through opening 878 such that whenthe merchandise system 810 is not in use, neither employees norcustomers can access the product.

It should be understood that the merchandise system 810 can be alteredsuch that first side wall 854 and second side wall 856 are reversed andthus, opening 878 is on the opposite side. As can be understood by onein the art, in this embodiment, the angled pusher face 892, frontretaining wall 876, and the lever 880, among other things, are alsoreversed.

Referring to FIGS. 90 and 91, in another embodiment, a housing 950defines a top wall 952, a first side wall 954, and an opposing secondside wall. A front edge of the base 812 is configured to mount to or ona rail 924 in any known manner. As discussed above, the base 812 mayinclude a rack and rack aperture wherein the rack defines a plurality ofteeth 990 (as shown in FIGS. 90 and 91) such that a gear of a gearassembly can be adapted to engage the plurality of teeth 990. The rail924 includes a front retaining wall 976 to retain product that is pushedtoward the rail. Front retaining wall 976 and housing 950 define anopening 978 that is roughly equal to the width of a single product. Thepusher 916 will urge the product toward the rail 924. When onemerchandise system 810 is be placed adjacent to another like merchandisesystem 810 on a shelf, product can only be removed through the topportion 979 of the opening 978. Accordingly, when product is positionedbetween the front retaining wall 976 and pusher 916, only a singleproduct can be accessed by customers or employees. It will be furtherunderstood that a device, such as a lever trigger (not shown), may beused to facilitate a customer or employee to partially or fully ejectproduct through the top portion 979 of the opening 978.

FIGS. 92A-101C illustrate another aspect of the invention, namely amerchandise system 1010. Similar to the other embodiments, themerchandise system 1010 improves product merchandising by limiting thenumber and the frequency with which product can be removed from, forexample, a merchandising shelf by using various methods such as anelectronic lock-out mechanism which locks the merchandising shelf andmultiple shelves when too many products are removed at one time. Themerchandise system 1010 may generally include a base 1012 and housing1050, a door assembly or door 1020, a locking assembly, and anelectronic control unit 1080.

The base 1012defines a front edge 1016, a back edge 1017, a first side edge 1018, asecond side edge 1019, and one or more tracks 1014. Additionally, thebase 1012 may include a ratchet shaft slot 1015. The ratchet shaft slot1015 may be configured to accept the ratchet shaft 1066 as will bedescribed below. The ratchet shaft slot 1015 may extend longitudinallyalong the length of the base 1012. The ratchet shaft slot 1015 is sizedand shaped to receive and mount the ratchet shaft 1066.

As is further illustrated in FIG. 92A, a housing 1050 can be mounted tothe base 1012 in any known mounting configuration and orientation. Thehousing 1050 defines a top wall 1052, a first side wall 1054, and asecond side wall 1056. The housing 1050 may also include a rearretaining wall (not shown in the figures). The first and second sidewalls 1054 and 1056, respectively, can be used such that when more thanone merchandise system 1010 is placed adjacent to another likemerchandise system 1010 on a shelf or stacked on top of another likemerchandise system 1010, product resting on the base 1012 of eachrespective merchandise system 1010 remains separated or divided. In anembodiment, one merchandise system 1010 can be stacked on top of anothermerchandise system 1010 without need of a separate shelf between the twomerchandise systems.

As shown in FIG. 92A, the one or more tracks 1014 may extend along thebase 1012 from the back edge 1028 to the door 1020. As shown, a track1014 can be used with a pusher 1040. It should be understood that moreor less than two tracks could be used with the invention, depending onthe particular application.

As illustrated in FIG. 92A, the one or more tracks 1014 extendlongitudinally along the length of the base 1012 and may define at leastone rail and/or an elongated aperture or channel in the base 1012. Thetrack is sized and shaped to receive and mount a mating element of thepusher 1040. The pusher 1040 may be slidably mounted to the base 1012such that the pusher 1040 does not lift out of the track 1014. Thepresent invention contemplates the use of other tracks to mount thepusher 1040 to the base 1012. Other pusher mounting techniques arepossible with the invention.

The pusher 1040 also contains at least one pusher urging element 1044used to urge the pusher 1040 toward the front of the shelf The pusherurging element 1044 may be any biasing element including, withoutlimitation, a flat coil spring or a spiral torsion spring. The presentinvention may use one or more pusher urging elements 1044 to urge thepusher 1040 depending on the desired application. The pusher urgingelement 1044 may be mounted to the pusher 1040 and the base 1012 usingany known mounting technique. In the exemplary embodiment, one end ofthe pusher urging element 1044 is secured to the base 1012 near thefront edge 1016 of the base 1012, and the opposing end of the pusherurging element 1044 is positioned behind the pusher 1040 to urge thepusher 1040 toward the front of the door 1020.

FIG. 98A illustrates a bottom view of the merchandise system 1010 in anunlocked condition. As is illustrated in FIG. 98A, similar to thedescription above for FIG. 93, the locking bar 1060 is not extended.Because the locking bar 1060 is not extended, the slot 1063 on thelocking bar 1060 presses against the locking end 1067 of the ratchetshaft 1066 and keeps the ratchet shaft 1066 in the position with thepusher lock 1068 resting on the smooth side of the ratchet shaft 1066.Additionally, because the locking bar 1060 is not extended, the lockingmember 1061 is not engaged with the locking latch 1064, thereby allowingthe locking gear 1062 to rotate freely and allow the door spring 1032 touncoil and the door 1020 to swing open.

FIG. 98B illustrates a bottom view of the merchandise system 1010 in alocked condition. As is illustrated in FIG. 98B, similar to thedescription above for FIG. 96, the locking bar 1060 is extended. Whenthe locking bar 1060 extends, the slot 1063 on the locking bar 1060presses against the locking end 1067 of the ratchet shaft 1066, therebyrotating the ratchet shaft 1066 such that the side with the plurality ofteeth 1069 faces upward and engages the pusher lock 1068. Additionally,when the locking bar 1060 extends, the locking member 1061 engages thelocking latch 1064, thereby moving the locking latch 1064 to engage withthe locking gear 1062 and the gear teeth. The locking gear 1062 cannotrotate clockwise, and thus the door spring 1032 cannot uncoil. Thislocks the door 1020 from swinging open.

FIG. 99 illustrates another feature of the merchandise system 1010,namely the operation of the door 1020. As is illustrated in FIG. 99, thedoor includes a first roller 1024 and a second roller 1026. The firstroller 1024 may slidably engage with an upper slot 1055 in the housing1050. The second roller 1026 may slidably engage with a lower slot 1057in the housing 1050. During the door operation, through the design ofthe first roller 1024, the second roller 1026, the upper slot 1055, andthe lower slot 1057, the back end and the floor of the door 1020 keepsthe next product behind the door from sliding forward. The door 1020continually contacts the product along the same vertical planethroughout the door's motion. As is shown in FIG. 99, through referenceletters “A” through “E”, the door operation is represented from theclosed position to the open position, with “A” representing the closedposition and “E” representing the open position. As illustrated by “A”,the first roller 1024 is positioned in the lower portion of the slot1055, the second roller is positioned in the lower portion of the slot1057 and the door handle 1022 is closed. As the door 1020 moves toposition “B”, as can been seen in FIG. 99, the first roller 1024 moves alonger distance along the upper slot 1055 than does the second roller1026 along the lower slot 1057. As the door 1020 moves to position “C”,the first roller 1024 has almost moved to the end of the upper slot1055, while the second roller 1026 has not moved much along the lowerslot 1057. As the door 1020 moves to position “D”, the second rollermoves a longer distance along the lower slot 1057, while the firstroller 1024 moves a smaller distance along the upper slot 1055. As thedoor 1020 moves to position “E”, the second roller 1026 again moves alonger distance along the lower slot 1057 to the final upper position inthe lower slot 1057 and the first roller 1024 moves a small amount intothe final upper position in the upper slot 1055. The design and shape ofthe upper slot 1055 and the lower slot 1057 combined together with thegeometry of the door 1020 allow the door to contact the product on thesame vertical plane throughout the motion of the door 1020, therebykeeping the next product behind the door from sliding forward. Once theproduct is removed from the door 1020 by the consumer, the pusher 1040and pusher spring 1044 will push the next product into the door 1020when the door 1020 returns to the closed position, thereby reloading thedoor 1020 with product.

As was described above, more than one merchandise system 1010 may beplaced adjacent to other like merchandise systems 1010 on a shelfAdditionally, the merchandise system 1010 may include an electroniccontrol unit 1080 to control the locking operations of all merchandisesystems linked together.
